BQ24232: BQ24232 Charger Protection Question.

Part Number: BQ24232
Other Parts Discussed in Thread: TPS22944

Hello,

I am working on a wearable project. I am using BQ24232 to charge my 1S Li-Ion battery.

To avoid problems like:

  • USB over voltage
  • ESD problems
  • High current drawing

Should I use a load switch (e.g TPS22944) after the BQ24232's output?

Or can the IC  handle this kind of problems?

Thank You.

Ahmet.

  • Hi Ahmet,

    The BQ24232 includes an OVP protection at 10.5 V and regulates the output to 4.4 V. For ESD, it has the following ESD ratings: 

    The device also features an output short detection which you can read about in the battery supplement mode section in the datasheet. 

    Best Regards,
